Whether you're just simply overseeding to keep your lawn thick and healthy, or you need to seed some areas that were damaged during the summer heat, now is the time.
Here are some ways to help make sure your seed gives you the results you're looking for this fall:
1) Make sure you incorportate your seed at least 1/4" into your soil. You can achieve this by using a slit-seeder or slicer. You can also aerate before seeding.
2) Keep the seed moist. Be careful not to over or underwater. The key is successful germination is to apply frequent and light watering to keep the seed moist and encourage quick germination.
3) Apply a "starter" fertilizer to encourage root development in the newly germinated seed. An example of a starter fertilizer is 18-24-12, one that is higher in phosphorus and preferably contains at least 40% slow release Nitrogen, to provide consistent feeding for the establishing grass.
4) Properly time your first mowing on the newly established grass. Wait until your new grass is about 2" tall and then begin mowing. Mowing will start to encourage the grass to thicken, giving you the dense turf you're looking for.
5) Keep the weeds out. Once you have begun mowing your newly established grass, be sure to control any broadleaf or grassy weeds that may emerge to ensure your grass to remain dense heading into the late fall / winter. This will help your lawn once Spring arrives to ward off spring-time weeds.
